The regular expression contains a back-reference …

[spiros]

I am trying both bulk and batch replace with a linked file. The linked file contents is 2 columns like this:

(?<!\[)ὥρη(?!\]) [[ὥρη]]
(?<!\[)ἥρῳ(?!\]) [[ἥρῳ]]

That is, find any such word if it is not followed by ] or preceded by [ and then create a [[wikilink]].

When I run this regex I get:
The regular expression contains a back-reference to a non-existent marked sub-expression

There is no problem when I run the regex normally from the find/replace dialog.

I couldn’t reproduce the issue. Which version of EmEditor are you using? Are you using the default regex engine (Boost.Regex)? Did you make any changes in the Advanced dialog box?

[spiros]

v. 21.9.915
default regex engine (Boost.Regex)
No changes in the Advanced dialog box

Is your linked file saved as UTF-8?

[spiros]

UTF-8 without signature, as the file in the screen

Please email me all your files after zipped so I will look into the issue.

I downloaded your files and tested, but I still couldn’t reproduce the issue.

I guess you have defined as conditions CR on the linked replacements file.

I did exactly the same way as the screenshot shows — “CR @”.
I don’t believe it’s an issue, but can you please try saving both your sample and linked file as UTF-16 with BOM, and see if you can still reproduce the issue?
